[Feature request] Support for cuFuncSetCacheConfig, cuFuncSetAttribute, etc.

These can be important for performance, depending on the application.

I think the most intuitive way to add this would be to add some options to prepared calls, but I don't know the codebase well.

cuFuncSetCacheConfig is supported: https://documen.tician.de/pycuda/driver.html#pycuda.driver.Function.set_cache_config

For the other functions that you find missing, I would welcome a PR.

Oh cool, I did not see this. I'll take a look and maybe model cuFuncSetAttribute off of this. Thanks!
